Epidemiology is the study of the causes and occurrences of disease and disability in the community and the application of this study to the control of health problems. This includes the investigation of outbreaks of communicable diseases, as well as the study of chronic illnesses. Information gathered through epidemiological studies and surveillance, along with district, state, and national data is collected, analyzed, and disseminated through reports and newsletters. The Cumberland Valley District Health Department and Cumberland Valley Region share a regional epidemiologist.
